sticky catchfly


The plant commonly known as sticky catchfly or clammy campion displays a clump-forming habit with a basal rosette of narrow, lance-shaped, green leaves. As it matures, the plant sends up erect stems that are sticky to the touch due to the presence of glandular hairs, which is characteristic of this species and the source of its common names. The foliage may sometimes take on a grey-green hue, providing a nice contrast with the flowers. The sticky catchfly is admired for its beautiful flowers, which are borne in dense clusters at the top of the stems. These flowers are typically vibrant pink and boast five petals that are deeply notched, giving them a somewhat fringed look. Each flower blooms atop a long stalk, which enhances its visibility and attractiveness. The blossoms tend to open in the late spring to early summer, presenting a showy display that can last for several weeks. The striking flowers are not only visually appealing but also serve as a draw for a variety of pollinators, including bees and butterflies. The sticky catchfly's charming appearance makes it a popular choice for gardeners looking to add a pop of color to rock gardens, borders, or wildflower meadows. The plant's sticky stems also serve a functional purpose, potentially trapping small insects that attempt to climb them, though this is not its primary means of pest control.

  • water dropWater

    Sticky Catchfly, commonly known as Lychnis viscaria, prefers consistent moisture, especially during its growing season. Water thoroughly when the top inch of the soil feels dry to the touch. This could mean watering every week, but it's important to pay attention to the plant's environment and weather conditions, as they can affect the watering schedule. During hot, dry periods, you may need to water more frequently. Generally, providing about one to one and a half gallons per week should keep the Sticky Catchfly satisfied, depending on the size of the plant and the pot.

  • sunLight

    For Sticky Catchfly, a spot with full sun to partial shade is ideal. It will thrive best with at least six hours of sunlight each day. Good light ensures healthy growth and optimal blooming. Be cautious of too much harsh midday sun if the plant is in an area that experiences extremely high temperatures, as this can sometimes stress the plant.

  • thermometerTemperature

    Sticky Catchfly does well in a range of temperatures but prefers moderate conditions. Temperatures between 60°F and 70°F are ideal for growth. The plant can survive minimum temperatures down to about 20°F, making it cold-hardy, but it will not fare well in temperatures exceeding 85°F.

  • scissorsPruning

    To encourage optimal health and blooms, prune Sticky Catchfly after flowering to remove spent blooms. This deadheading process can stimulate a second flush of flowers. Cut back the foliage in the fall, as the plant goes dormant, to maintain a tidy appearance and prepare it for new growth in the spring. Pruning can be done annually, or as needed to remove dead or damaged stems.

  • circleLife cycle

    Lychnis viscaria, commonly known as Catchfly or Sticky Catchfly, begins its life as a seed that germinates when soil temperatures and moisture levels are adequate, typically in spring. Seedlings develop into rosettes with oblong leaves, experiencing vegetative growth throughout the first season. The plant enters a period of dormancy during the winter months, particularly in colder climates, conserving energy by dying back to the ground. In the following growing season, Catchfly produces flowering stems that range in height, topped with clusters of pink or crimson flowers from late spring into early summer. After pollination, typically by insects attracted to the sticky substance on the stems that gives the plant its name, the flowers develop into capsules containing small seeds. The mature seeds are dispersed, either naturally or by human intervention, completing the life cycle and allowing for new Catchfly plants to establish.

    • Propogation time

      Spring-Early Summer

    • Propogation: Lychnis viscaria, commonly known as the sticky catchfly, is often propagated by seed. The best time to sow seeds is in early spring after the last frost when the soil is workable. Sowing the seeds can be done directly in the garden where they are to grow. The seeds should be scattered on the surface of well-draining soil and pressed lightly into the soil, without covering them as they require light to germinate. Consistent moisture should be maintained until germination, which usually occurs within 2 to 3 weeks. Sticky catchfly can also be propagated by dividing mature clumps in the spring or autumn, but seed sowing remains the most popular due to its simplicity and effectiveness.
